The last time I upgraded smail, I found that it would no longer behave properly. It seems, however, as if the config scripts are set up deliberately to to specify this misbehavior.
Specifically, when set up to use a "smarthost" mail server, it insisted on sending mail intended for "root", such as cron reports, to that mail server as well. (My ISP admin is less interested my cron reports than I am.) I gave up, purged Smail, and installed Exim, and now all is well. Maybe that was the point. Nathan Myers [EMAIL PROTECTED]
